It is recommended that you show work in progress each week. Aim to have everything animated by Week 14 so you can spend the following week on revisions and polish. Playbasts are fine. No rendering required.

Videos:
Quicktimes, 560 pixels by 316 pixels, H.264 codec, max 10MB. You can use a variety of tools such as Handbrake, Adobe Media Encoder, Quicktime Pro and more to format your videos. I use the 11-second club guidelines for all submissions:http://www.11secondclub.com/helpful_hints/encoding

As you approach the end of your program, here's a good question to start asking yourself?
'What is your workflow?'. The idea of WORKFLOW in animation is a very personal one.

Generally most animators will do at least most of the following:

read the script/watch the leica/look at the storyboard

draw some thumbnails for key actions

act out the scene on video

block the broad strokes of their shot using stepped keys or very pose-to-pose timing

approval or peer review

start breaking it down

approval or peer review

add polish, layering, offsetting

final approval

revisions or retakes

Some variations:
- key all controllers on each pose, adding all the detail needed to sell the posing
- key only the basic controllers on each pose and layer the complexity in subsequent passes
- work straight ahead keying only the main controls and adding finer detail in subsequent passes

.. and there are more where that came from.

With 3D, it's important to stay SIMPLE because of the complexity of fixing animation on several controllers moving on different frames. That said, you need to show the director what you're planning, and that means adding even expressions and finger controls from a very early stage.

What you don't want to do is randomly start working without any plan. Think! Plan, then start animating. "Measure twice, cut once"
